Abstract
A catheter and catheter system for eccentric remodeling and/or removal of atherosclerotic material of a blood vessel of a patient include an elongate flexible catheter body with a radially expandable structure. A plurality of electrodes or other electrosurgical energy delivery surfaces can radially engage atherosclerotic material when the structure expands. An atherosclerotic material detector near the distal end of the catheter body may measure circumferential atherosclerotic material distribution, and a power source selectively energizes the electrodes to eccentrically remodel the measured atherosclerotic material.
